Welcome!

I believe you are looking for Strategy Zone;
That's where all the competitive talk is.
It's a little slow, but maybe you can help liven it up!

And as far as the "reset" definition goes: I get confused to as I keep thinking it has something to do with resetting frame disadvantage.

I think the appropriate definition though is:

It's a product of the damage scaling system. The longer your combo lasts, the less damage it will do towards the end, so all combos have an upper limit on the amount of damage you can inflict. Theoretically, if you had them in an infinite time would run out before they died.

However, you can create scenarios where your combo is briefly interrupted, resetting the damage scaling. This way you can rack up a ton of damage in one push. The downside is that you are giving your opponent a chance to break free.

It's a risk/reward thing. You're risking a guaranteed bit of damage at the end of your combo for a much greater amount of damage if you think you can trick your opponent into blocking the wrong way.

Ah ok that makes sense, what about all the other crazy words flying around here lol? And thx for the welcome dude!

What crazy words?

As for other terminology, what would you like to know? There's not a lot, but there's a respectable amount of people knowledgable on the subject.
